If the style is embedded in your Element you just have to use .attr("style") .
JSoup is not a Html renderer, it is just a HTML parser, so you will have to parse the content from the retrieved <style> tag html content. You can use a simple regex for this; but it won't work in all cases. You may want to use a CSS parser for this task.
public class Test {
public static void main(String[] args) throws Exception {
String html = "<HTML>\n" +
"<HEAD>\n"+
"<TITLE>Page 1</TITLE>\n"+
"<META http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">\n"+
"<DIV style=\"position:relative;width:931;height:1243;\">\n"+
"<STYLE type=\"text/css\">\n"+
"<!--\n"+
" .ft00{font-size:11px;font-family:Times;color:#ffffff;}\n"+
" .ft01{font-size:11px;font-family:Times;color:#ffffff;}\n"+
"-->\n"+
"</STYLE>\n"+
"</HEAD>\n"+
"</HTML>";
Document doc = Jsoup.parse(html);
Element style = doc.select("style").first();
Matcher cssMatcher = Pattern.compile("[.](\\w+)\\s*[{]([^}]+)[}]").matcher(style.html());
while (cssMatcher.find()) {
System.out.println("Style `" + cssMatcher.group(1) + "`: " + cssMatcher.group(2));
}
}
}
Will output:
Style `ft00`: font-size:11px;font-family:Times;color:#ffffff;
Style `ft01`: font-size:11px;font-family:Times;color:#ffffff;

Try this:
Document document = Jsoup.parse(html);
String style = document.select("style").first().data();
You can then use a CSS parser to fetch the details you are interested in.
